I am working on a dynamic feature where a report is loaded in a reportviewer. I have a dropdownlist where the user can select one of the reports. The selected report is then loaded in the viewer.
Each value in the dropdownlist called ddl1 is the name of the reporting class that I want to view. For example, a user selects "InvoiceReport"...I would like the following to happen.

ReportViewer1.Report = new InvoiceReport();
I am unable to accomplish this because this is the code I have.
string strddl = ddl1.SelectedItem.Value + "()";
ReportViewer1.Report = new strddl;
Or I have been trying to do this as well...
Telerik.Reporting.Report report = (Telerik.Reporting.Report)ddl1.SelectedItem.Value;
How do I pass in the string value of the report name into the reportviewer1.report loading declaration?
Have any ideas?
Thanks

Hello Tom,
It is not clear what programming language you're using but the easiest way to create an object from a string with .NET is to use reflection. Have in mind that you have to use the assembly qualified type name. Here is a code snippet in C# that demonstrates this technique:
string typeName = "MyNamespace.MyReport"; // replace this with your specific report type assembly qualified name
Type reportType = Type.GetType(typeName);
MyReport report = (MyReport)Activator.CreateInstance(reportType);
In case you want to learn more about the Activator.CreateInstance() you can start reading from here.
